Solution Overview

Problem

Conventional solutions for supporting successful handover reports in 5G NR networks are inefficient, as they generate reports for every handover, leading to unnecessary resource waste and increased processing complexity, without clear mechanisms for configuring these reports.

Innovation Solution

A method where a terminal device receives a report configuration from a network device indicating whether to generate a successful handover report, allowing the report to be generated only when necessary, based on conditions such as radio link monitoring or beam failure detection, thereby optimizing resource usage and reducing signaling overhead.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If successful handover reports are generated for every handover, then data collection for SON features is improved, but resource waste and processing complexity increase

Engineering Contradiction:
Improvedata collection for SON featuresVSAvoidresource waste
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent introduces a report configuration parameter that can be set to enable or disable successful handover report generation. This parameter allows the system to change its behavior based on operational needs, generating reports only when necessary (e.g., when handover issues are detected or when SON optimization requires the data), thereby reducing unnecessary resource consumption while maintaining data collection capability when needed.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system dynamically adjusts report generation based on configured conditions rather than generating reports uniformly for all handovers. The report configuration can be updated in real-time based on network conditions, allowing the system to adapt between high data collection mode (when issues are detected) and resource-saving mode (when handovers are successful and routine), resolving the contradiction between information completeness and resource efficiency.

Inventive Principle:
Principle #15Dynamics

2Reliability

If successful handover reports are generated for every handover, then mobility robustness optimization is improved, but device complexity increases

Engineering Contradiction:
Improvemobility robustness optimizationVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The report configuration parameter serves as a control switch that simplifies processing by clearly defining when report generation is required. Instead of continuously processing all handovers, the system only activates the complex report generation and analysis functions when the configuration enables it, reducing processing complexity while maintaining mobility robustness optimization capability when needed.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts the successful handover report generation function as an optional, conditionally-executed module rather than a mandatory continuous process. By separating the report generation logic from the core handover execution, the system can maintain mobility robustness optimization through selective report collection while significantly reducing the complexity burden during routine handovers when reports are not required.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If successful handover reports are generated for every handover, then handover optimization is improved, but signaling overhead increases

Engineering Contradiction:
Improvehandover optimizationVSAvoidsignaling overhead
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The report configuration parameter acts as a control mechanism that adjusts the quantity of signaling messages exchanged during handover. When the configuration enables successful handover reports, the system generates and transmits detailed reports for optimization purposes. When disabled, the system reduces signaling overhead by omitting these reports, thereby resolving the contradiction between handover optimization productivity and signaling overhead quantity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Instead of generating complete handover reports for all handovers (excessive action), the system applies partial action by generating reports only for specific handovers that meet configured criteria (e.g., handovers involving issues, handovers to specific cells, or handovers where SON optimization is actively needed). This selective approach maintains handover optimization effectiveness while significantly reducing the overall quantity of signaling overhead.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Embodiments of the present disclosure provide a solution for supporting a successful handover report. In a method for communication, a terminal device receives a report configuration from a first network device providing a first cell. The report configuration indicates whether a successful handover report is to be generated for a handover of the terminal device from the first cell to a second cell of a second network device. Then, the terminal device applies the report configuration during performing of the handover. Through the embodiments of the present disclosure, the terminal device may be limited to reporting a successful handover report if the source network device considers the successful handover report as necessary, thereby saving the processing resources and communication resources for the potentially unnecessary successful handover reports.
